ScheduleID is an int in my stored procedure. SoI inserted the (int.Parse) But now I get that error. How can I convert an int into the QueryString.?If I take out the (int.Parse) The method I have calling the above. Its something like:

I have a Data field of type "Integer" below is my Edit Template for this Data field
<asp:TextBox
ID="OfficeSqFtTextBox"
runat="server"
Text='<%# Bind("OfficeSqFt", "{0:#,0}") %>'
Here is my problem When I try to edit this record, in the Edit mode, this Data field shows the number correctly with formatted e.g. 22,344 if I click on Save the record, it will give me the error "Input string was not in correct format". If I edit this number and remove the "," between numbers then it saves. What can I do to make this work? If I remove the "{0:#0}" then in the edit mode the number will show as 22344 without any comma separation. Note: On the same page I have other Data field of type "Money" and it works with the format applied ???? why does it works with the Money type and not Int???

Is it legal to define a default value for a parameter the way I am in the code below? It keeps throwing an "Input string was not in a correct format." error for me. Is there a different way I should be doing this?
<asp:LinqDataSource ID="lds_numbers" runat="server" ContextTypeName="nrm.prop.myDataContext"
TableName="Sources" Where="myNumber== @myNumber" EnableDelete="True"
EnableInsert="True" EnableUpdate="True">
<WhereParameters>
<asp:Parameter DefaultValue='<%= this.StateItems["myNumber"] %>' Name="myNumber" Type="Int32" />
</WhereParameters>

I got a "Input string was not in the correct format" exception but can't see the problem. The exception had no information to show what was causing the error. It's thrown before the BLL or DAL are called so it must be in the mark up. The parameters are in the right order.[Code]....

I've got a Dropdownlist with CategoriesI've also got a Listbox with Items filled using the selection from the DDL (autopostback=true).I have a SQLDataSource for each one.the DDL populates perfectly. the listbox SQL DataSource uses a stored procedure, that, on its own works perfectlyIt works well just as outlined above. However, when I add the following properties to the DDL, I get an error:
appendDataBoundItems=true and '--Select--' (tried 'Select' also) as an item
the error is:Input string was not in a correct formatI also set up the sqlDataSource selecting event handler, so that it would check for 'Select' first, but it bypasses that handler when debugging, and goes straight to the error msg

I get the Erorr: Input String was NOT a correct format.
The first three controlparameters are STRINGS and they work fine.
However the last two populate the controlparameter from text boxes that can only accept numbers and decimal point.
First the text boxes for {3} and {4} string parameters in the SQL filterexpression:
[Code]....
And then the SQLDatasource control parameters[Code]....
The last two control parameters are the ones is question as they feed {3} and {4} parameters in the filter expression, NOTICE how I set the type="double".The data input is expected to be like 152.25 or 3.6 or 4 etc,So why am I getting this error: [Code]....

I have gridview control that has data binded by using EF. Whenever I try to sort my gridview I get this error: "Input string was not in a correct format." This error points to the following line of code: "int index = Convert.ToInt32(e.CommandArgument);"

I'm not sure what do I have to fix if I want to sort the columns.
If I bind the data manually what is the code for codebehind to allow sorting for particular columns.

I'm retreiving information from a Progress database and databinding it to a repeater control. The line with repeater1.databind() gets an error saying "Input string was not in a correct format". The weird thing is that I only get it for one specific date, ie. when I choose rows based on a date in a specific column. That would suggest there is something wrong with the data in these rows, but I cant find anything. And you basically can not put anything "corrupted" in it, its a commercial system which I have not developed myself.
What are the possible reasons for this error? Why does it trigger on databinding and not when, for instance, I try to convert a value?

I have a gridview that was displaying and handling postbacks correctly, that is, until I upgraded to .net 4.0 (vs 2010) from .net 3.5. Now I am getting the classic (and in this context meaningless) "Input string was not in a correct format" error upon postback. The postback is initiated by a command button and the row command event handles everything nicely.
The trace shows internal grid postback handling and nothing else:
[FormatException: Input string was not in a correct format.]
System.Number.StringToNumber(String str, NumberStyles options, NumberBuffer& number, NumberFormatInfo info, Boolean parseDecimal) +9594283
System.Number.ParseInt32(String s, NumberStyles style, NumberFormatInfo info) +119
System.Convert.ToInt32(String value, IFormatProvider provider) +48
System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +1047....
From experience, I know this happens on late binding with wrong type casting on the ASPX side of things. However, nothing has changed. The code is the same, the only thing that changed is the upgrade to 4.0.
I have tried everything I (and a coleague) can think of to figure out what the issue is without luck. No error is raised on the code behind in any method. The only error raised is the Page_Error event and the error object contains the same crap you see in the yellow screen dump (above).
UPDATE: I narrowed the issue down to the RaisePostBackEvent method. I had to reflect the System.Web (for educational purposes of course :) assembly to figure out the code executing after my RowCommand logic(which is fine) breaks. This happens in the HandleEvent method. It checks for known command names (e.g. Select) and if it can't find a match, it defaults to the following:
[Code]....
Is this a bug or am I doing something wrong? The row object is NULL which is why it defaults to the cast. The cast assumes the argument to be an integer however and in my case I am passing a string as an argument?
